摘　　要：目的:探讨多平面重建技术在上颌后牙区剩余牙槽骨测量中的应用价值。方法:收集30例上颌后牙区缺失牙患者行颌面部螺旋CT平扫后进行多平面重建及Dentascan软件成像,分别在两种成像方法的图像上对缺牙区可用骨的高度、宽度及骨密度值测量。结果:在多平面重建的CT图像上测量结果与Dentascan软件成像测量结果比较均无显著性差异(P>0.05)。结论:多平面重建技术能准确地评估剩余牙槽嵴骨量及骨质情况,对上颌后牙区牙种植术前设计具有重要指导意义。Objective: To explore the value of multiple planar reformation technique in the measurement of maxillary posterior-tooth area residual alveolar ridge.Methods: MPR and Dentascan software imaging of spiral CT scan from 30 cases with missing tooth of maxillary posterior-tooth area.The edentulous area available bone height,width and bone mineral density were maesured on the imaging respectively.Results: No statistically significant differences was found beteween the MPR and Dentascan software imaging(P>0.05).Conclusion: Multiple planar reformation technique can accurately evaluate the bone mass and bone mineral density of the residual alveolar ridge.For the patients with missing tooth of maxillary posterior-tooth area who want to do the implantation the MPR can provide important guiding significance before dental implantation design.
